I would never do that personally. Someone is looking for information about how my business can help their business, I'll talk to them about it. However, many in the thread prefer and sometimes require the initial discussion to take place over email. Maybe, I do not understand the SEO business. But in my business, I need to first learn about the client, the challenges they face, and get a feel of what they are willing to do to solve those challenges.

At the end of the call, I normally tell them that I will email them with more detail, on what I think will benefit them. Not the other way around. I put the effort into the initial call. Why? Because often, they do not understand what they need, because they do not know what options are available to them.

Again, this is just me. I have enough business at the time to turn people away. But, it does not mean that I turn my shoulder. Note, I am not saying that the people in the thread treat prospects wrong, I might have read the thread totally wrong. Read it for yourself here.
